(+)-Penbutolol

(+)-Penbutolol is a β-adrenoceptor antagonist, with an IC50 of 0.74 μM[1]. (+)-Penbutolol is an optical isomer of l-penbutolol with Na+ channel-blocking action[2].

IC50: 0.74 μM (β-adrenoceptor)[1].

(+)-penbutolol on the [Ca2+]i-increase induced by LPC is concentration-dependent[1]. (+)-penbutolol inhibits the rounding of cells dose dependently (8±4%, 56±4% and 66±2% at the concentrations of 10-6 M, 5×10-6 M and 10-5 M, respectively)[2].
